NCERT Exemplar for Class 10 Maths Chapter 5 – Arithmetic Progressions
NCERT Exemplar Solutions for Class 10 Maths Chapter 5 Arithmetic Progressions provide a detailed explanation of sequences and patterns that form an essential part of algebra and real-life applications. This chapter introduces students to arithmetic progressions (AP) and helps them understand how to calculate specific terms and sums efficiently. The chapter begins with the definition of an arithmetic progression, where the difference between consecutive terms remains constant. Students learn how to find the nth term of an AP using the formula an = a + (n – 1)d, which is crucial for solving direct as well as application-based problems. The solutions provide step-by-step explanations that make the process of identifying terms and solving AP-based questions simple and logical.
Another important topic covered is the sum of n terms of an AP. Through various exemplar problems, students practice how to use formulas such as Sn = n/2 [2a + (n – 1)d] and Sn = n/2 (a + l) effectively. These concepts are further reinforced with real-life application problems such as calculating savings, distribution of resources, and analyzing repeated patterns. The NCERT Exemplar Class 10 Maths Solutions focus on higher-order thinking questions that test analytical skills and help learners go beyond basic textbook practice. By solving a variety of questions, students develop accuracy, logical reasoning, and confidence for exams. This chapter is especially useful for CBSE Class 10 board exams, where AP-related questions are frequently asked in both direct and applied formats. Additionally, mastering arithmetic progressions prepares students for higher-level topics in sequences and series at the senior secondary level. Overall, NCERT Exemplar Solutions for Class 10 Maths Arithmetic Progressions ensure that learners develop a strong foundation, making them exam-ready while also improving their problem-solving ability in real-life contexts.
